Dr Tassos Dimitriou is affiliated with the Department of Computer Engineering at Kuwait University (KU) and the Research and Academic Computer Technology Institute (CTI) - Greece, where he is an adjunct Senior Researcher in the Research Unit 1. Dr Dimitriou is interested in various aspects of Theoretical Computer Science like combinatorial optimization, design and analysis of heuristics/probabilistic algorithms for difficult to solve problems, sensor and RFID networks, computer and network security (especially why the latter is so difficult to achieve in real life...).


Prior to that,  Dr Dimitriou was an Associate professor at Athens Information Technology - Greece and adjunct faculty of Information Networking Institute at Carnegie Mellon University, USA. At AIT he was leading the Algorithms and Security group where the primary objective was to bring together expertise in education, research and practice in the field of information security and algorithms, conducting research in areas spanning from the theoretical foundations of cryptography to the design and implementation of leading edge efficient and secure communication protocols. A brochure and a snapshot of this research which is still ongoing can be seen here. Dr Dimitriou was also the organizer of PRACSE, a semi-annual event event focusing on issues related to important properties of systems and business security, however, with an emphasis on practical aspects of security. Further evidence to the importance of PRACSE is given by its list of eminent academics, professionals and keynote speakers that regularly participated in the event!


Dr Dimitriou's research in the above fields has resulted in numerous publications, some of which received distinction, and numerous invitations for talks in prestigious conferences like the International World Wide Web conference and InfoCom. Furthermore, apart from his usual academic admin/teaching/research duties, he regularly consults with companies on topics related to security and he gives short and professional courses aimed at professionals and people who want to become familiar with the exciting field of network security.


Dr. Dimitriou is a senior member of IEEE, ACM and a Fulbright fellow. He is also a Distinguished Lecturer for ACM.





Here are some recent conferences that I'm somehow involved. Older activities can be found here.





The Black Hat Collection


BlackHat USA - SpySense Spyware Tool

...Spy-Sense is a spyware tool that allows the injection of stealthy exploits in the heart of each node in a sensor network. Spy-Sense is undetectable, hard to recognize and get rid of, and once activated, it runs in a discrete background operation without interfering or disrupting normal network operation.



BlackHat Europe - Sensys Attack Tool

...SenSys is the first instance of an attack tool that can be used by an adversary to penetrate the confidentiality of a sensor network. It can analyze overheard radio messages and use this information to perform attacks such as Sinkhole, Replay/Modify Data, Selective Forwarding, Malicious Code Injection, etc... For more information, check out the Sensys web site!!!

Running for fun (but not profit)


Back in March 2010, I made a potentially life changing decision: I signed up for the 28th Athens Classic Marathon, honoring the 2,500 years anniversary from the Marathon Battle. Running a Marathon was something of a "dream" when I started running a couple of years ago, but always felt like a mission impossible... Most probably this challenge would prove to be way out of my league, but I figured if there was ever a time, that would be it! Fortunately, I was good for the challenge... So, here are some pictures from my first Marathon race... (as well as a couple of subsequent ones...). Since then I ran a few more but I stopped posting them here... :-)
